Statements: All flowers are trees. No fruit is tree.
Conclusions:
- No fruit is flower.
- Some trees are flowers.
Answer: Option
Explanation:
As discussed above, the conclusion must be universal negative and should not contain the middle term. So, it follows that 'No flower is fruit'. I is the converse of this conclusion and thus it follows. II is the converse of the first premise and so it also holds.

It means that the first premise can be viewed from another angle
For eg.
The converse of the statement all A are B is
1. Some A are B & 2. Some B are A
Also Some A are B can be written as Some B are A.

As per Rule 1 "The conclusion does not contain the middle term". How can second conclusion be true as it is containing middle term "Tree"?

'2' can't follow as it contains the middle term. Answer should be [A]. Please advise.
